  2. Lung cancer staging - Wikipedia

    en.wikipedia.org/wiki/Lung_cancer_staging

    From there it spreads in fairly predictable pattern. Typically, if lung cancer spreads, it first goes to nearby lymph nodes, followed by lymph nodes further away located between the lungs in a space called the mediastinum. In the mediastinum, the lung cancer tends at first to stay on the side where the original tumor started. Once it crosses ...

  3. Cancer survival rates - Wikipedia

    en.wikipedia.org/wiki/Cancer_survival_rates

    In males, researchers suggest that the overall reduction in cancer death rates is due in large part to a reduction in tobacco use over the last half century, estimating that the reduction in lung cancer caused by tobacco smoking accounts for about 40% of the overall reduction in cancer death rates in men and is responsible for preventing at least 146,000 lung cancer deaths in men during the ...

  4. Limited-stage small cell lung carcinoma - Wikipedia

    en.wikipedia.org/wiki/Limited-stage_small_cell...

    Small cell lung cancer is often treated as a systematic disease due to its tendency for early dissemination, [4] thus, instead of the traditional TNM staging system, the Veterans' Administration Lung Study Group (VALSG) introduced a simplified 2-stage system in the 1950s to divide small cell lung cancer into limited stage and extensive stage. [7]

  5. Five-year survival rate - Wikipedia

    en.wikipedia.org/wiki/Five-year_survival_rate

    Five-year survival rates can be used to compare the effectiveness of treatments. Use of five-year survival statistics is more useful in aggressive diseases that have a shorter life expectancy following diagnosis, such as lung cancer, and less useful in cases with a long life expectancy, such as prostate cancer.

  6. Hemiacetal - Wikipedia

    en.wikipedia.org/wiki/Hemiacetal

    In organic chemistry, a hemiacetal is a functional group the general formula R 1 R 2 C(OH)OR, where R 1, R 2 is a hydrogen atom or an organic substituent. They generally result from the nucleophilic addition of an alcohol (a compound with at least one hydroxy group ) to an aldehyde ( R−CH=O ) or a ketone ( R 2 C=O ) under acidic conditions.

  7. Interstitial lung disease - Wikipedia

    en.wikipedia.org/wiki/Interstitial_lung_disease

    Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...

    In 2016, the WHO recorded 56.7 million deaths [3] with the leading cause of death as cardiovascular disease causing more than 17 million deaths (about 31% of the total) as shown in the chart to the side. In 2021, there were approx. 68 million deaths worldwide, as per WHO report.

  9. Lymphangioleiomyomatosis - Wikipedia

    en.wikipedia.org/wiki/Lymphangioleiomyomatosis

    Video-assisted thoracoscopic lung biopsy is the most definitive technique, but transbronchial biopsy has a yield of over 50% and can also be effective. [82] [83] The safety of the latter procedure in patients with diffuse cystic disease and the profusion of cystic change that predicts an informative biopsy are incompletely understood, however ...
